Changes in to an entity should not reflect in already created diagram

[h_faheem]

Hello All

I am struggling with diagrams in Sparx EA.
I need to create diagrams for every project that comes in the company. I have to use same components for many diagrams. I will try to explain my issue using an example:

I have three components A, B, C which represent three different applications.

Project-1 requires me to create and integration link from A to B and then B to C. This i create in a diagram. So now in this diagram, i have three applications/components where A is linked to B and B is linked to C.

Later on another project, say project - 2 comes in, which requires me to create a link from A to C. I create this in a new diagram.

This issue is that when i create a link from A to C; it also starts showing automatically in Diagram that is created for Project-1.
      I need Project-1 diagram only to show project specific integrations. So no other changes should automatically reflect in Project-1 diagram unless i change Project-1 Diagram explicitly.

Is there any solution to this?

You can hide the relationship in a the diagram you don't want to show it on.
Right click on the relationship and from context visibility>hide

It seems to me that the A in Project-1 is not the same A as the A in Project-2 (evidence: the A in Project-1 doesn't have a link to C). Therefore they need to be separate elements. Try creating instances of A and using those. (Ctrl+Drag A from Project Browser onto diagram and select "Instance" instead of "Link").

Thanks for the comments.

A in both projects is same application

A model is a view of a [mythical] now state.  Your project 1 is a past state and your project 2 is a future state.  If you want them to be different you need to model them differently.  A diagram is not a picture (although your project 1 issue could be consider akin to Dorian Grey).
